13e it known that I, ,ALBERT Y. EDWARDS, aalcitizen of the UnitedStates, residing at efSpringield, in the county of Clark and vvState ofOhio, have invented certain new 1w; and useful Improvements in.Explosive-Engilles, of'which the following is a specifica `ition. U a.la-My invention relates to improvements in IQnexplosive engines and itrelates more parneticularly to im rovements `in the arrangement of theexliaust and inlet valves and the cylinder head.- u Y a- 1 The object ofthis invention is to provide lianA arrangement of the cylinder head andliff Ythe inlet .and exhaust valves so that valves l lof large area maybe used in their proper ,relati'on` to each other and to the piping or',conduits leadin therefrom; the arrangefment being sucfh that thevalves will be readily accessible Without disturbing the mother partswhich operate in connection Utherewith. i

f A further object of my invention is to so arrange these parts thatthey can be fully f a andcompletely protected by water jackets and theparts thus be kept cool.

I attain these objects and others, which mwill more clearly appear fromthe followingv .30 description, by the construction shown' in y theaccompanying drawings inwhicli Figure l is a plan view of l,an explosiveengine of a three-cylinder type, to which 'my improvement has beenapplied, one of the cylinders and 'its head being shown in f section.Firr. 2 is a side elevation, partly in "section, of the upper portion ofone of the *cylinder heads showing the arrangement of ifthe supply andexhaust ports. Figs. 3 and 404.- are detail views in'section showing thearrangement and construction for supplying `Water to the jacketed valvesand the means for disconnecting the same to permit a removal of thecylinder head and valves with out disturbing the piping. Fig. 5 is asectional'elevation of a cylinder head showing the valve chambers andvalves.

Like'parts are represented by similar letfters ofy reference in theseveral views.

In the saiddrawings a1, a2, 'as represent f the various cylinders.4 Z)is the gas supply -V" pipe or conduit which leads to these variouscylinders through branch connections 51,?52, ba. "d is thefexhaust pipeVwhich connects COMPANY, or SPRINGFIELD, omo, A CORPORATION or `orgianxPLosIvn-ENGINE.

Y upper or outer end Ports b4 leading-from Patented May with therespective cylinders in asimilar-.55 manner through branchesy c1,- 02,es: These connections, both for thevinlet and the exhaust, are made in.an suitable manner with the side of the cylin er preferablynearits therespectivel supply pipes b1, '62,' bfua'nd similar ports c* tol theexhaust,pipesfovc2 es are formed in the side of the cyl-'nder ansurrounded by the cylinder water'ja'ckets'a. Both the su ply andexhaustvalves e and f are locate in the 'cylinder head g,'vvhich is of apeculiar construction, that is,it is formed of sufiicient length toreject into the cylinder beyond the point W '1ere the inlet and outletports, b4, 0*, pass through vthe I70 walls of the cylinder and t ecylinder head is provided with similar portae1 and 1, which registerwith the ports, 6*, c", in t e sides of the cylinder so thatI the supplyand exhaust, to and yfrom the valves, pass later-l ally through the'Walls fof thecylinder and into the chambers formed in the cylinder headg. Each of the cylinder heads are identical in construction, henceadescri tion of one answers for-a description of ail.' Surroundingthelports e1 and f1 and the valves, the valve chambers and the valvestems is a Water jacket, g1f,inthe cylinder head, which issuitably'connected,l ina manner hereinafter describetk"withf'the -Watercirculation which keeps all' of the'fp'arts cool.'

The connection between theoutsideoffthe a f cylinder-head and the insideof 'the cylinder is preferablyformedbymeans of a ground joint, theparts'being accurately" fitted' so that, when in proper position, atight -fjoi'nt is secured Without the aid of packing materia] of anykind: lThe valves are-openjand closed to admit the supply and'permit thedischarge of the exhaust, in any suitable manner, preferably by the"employment of an arm g2, supported o'na bracket g3 -on thecylinder-head which arm connectsdirectly with the valve Stems g4, asuitable detachable connection, g5, being 'arranged'between the ,-100end of this arm and the valve voperating rod f` or connection g. Thecylinder head will bea-preferably formed with the usual flange g? andsecured in place b the usual bolts g8. It is one of thespeclal `featuresof' importance in engines of'this kind tobe able to have access tothevalves and` the,oy`linder without the necessity of'f'diseonnecting fthe'supply and exhaust pipes or both, and for the water to the Water jacket.It is also desirable (that the water chamber completely surround thevalve chambers and also be capable of being drained. To accomplish thisI form a connection through the cylinder Wall and through the outer wallof the 'cylinder head, as shown in Figs. 3 and 4, and in this opening Iinsert a hollow sleeve or' plug It having at its inner end a joint k1preferably ground to fit a similar opening in the outer Wall of thecylinder head, thus `making a tight joint between the said cylinder headand the said plug or sleeve without the aidof packing material of` anykind.'`

This plug or sleeve is preferably provided with flanges ha and bolts h4,by means of which it is securedin place after the manner of a gland. Tothe outer end of this plug 2o or sleeve is secured the circulating pipefrom the Water supply h5, this connection` furnish a device in whichvalves of large area for the inlet and exhaust are provided which may beplaced in close proximity and side by side, also the valves, chambersand stems are completely surrounded by a water jacket :1nd,bydisconnecting the arm gzat g5 and .cylinder-head, with the valves, eanberemoved Without disturbing any of the other parts. In disconnecting thewater connection z. it is only necessary to loosen the same sufficientlyto allow the end of the sleeve or connection It to be withdrawn to apoint within the inner periphery of the cylinder', which will bepermitted bythe resiliency of the pipe connection h5 without any otherdisconnection. Further, by lhaving the plug h communicating with theextreme lower end of the Wat'er jacket of the cylinder head, the headmay be completely drained, and, also, by the construction described, thehead may be drained entirely-independent of the cylinder jacket. Theadvantages of this construction are obvious and, other than mentioned,need not be described in detail.

' The supply and exhaust are permanent and pass laterally through thewalls of the cylinder and connect withl the lateral ports in thecylinder-head and thus direetlly to the valves, securing large andsimple passageways free from friction and insures both a perfect exhaustand inlet. The ease and facility of 'the removal-of the cylinder-headwithoutl disturbing the other parts, while keeping all'of vthe partscompletely waterj acketed, is especially advantageous.

the Water connections jl and L, thev Having thus described my invention,I claim:

l. `The combination of'a cylinder and a removable extended cylinder headlocated in the end thereof, a water jacket for said cylinder and a waterjacket for said head, said jackets being independent of each other andnon-communicating, and a water connection for said head water jacketextending through the walls of said cylinder, substantially asspecified.

2. The combination of a cylinder and a removable extended cylinder headlocated in the end thereof, inter-communicating ports between thecylinder and head, anindependent water jacket for each of said parts,said jackets being non-communicating, and a Water connectioncommunicating with the head water jacket vand extending through thejivals of said cylinder, substantially as speci- 3. The combination of acylinder and a removable extended cylinder head located in the endthereof, independent non-communicating water jackets for said head andcylinder, respectively, and a water connection communicating with thelower end of the water jacket flor said head and extending through thewalls of `said cylinder, substantially as specified. i
